0115 This enables a workaround for erratum CPU15 on MPC8xx chips.
0116 This bug can cause incorrect code execution under certain
0117 circumstances. This workaround adds some overhead (a TLB miss
0118 every time execution crosses a page boundary), and you may wish
0119 to disable it if you have worked around the bug in the compiler
0120 (by not placing conditional branches or branches to LR or CTR
0121 in the last word of a page, with a target of the last cache
0122 line in the next page), or if you have used some other
0123 workaround.
